Abstract: A container has a body portion, a collapsible portion, and an outlet aperture arranged on the collapsible portion, in which the collapsible portion is collapsible from a start configuration in which the outlet aperture is aligned with an axis, to a collapsed configuration in which the outlet aperture is rotated from the axis, in which the collapsible portion has a bracing section which is shaped and configured to support the collapsible portion against collapse when the outlet aperture is subjected to a first force applied in line with the axis, and in which the collapsible portion has a structurally weakened section which is shaped and configured to fail in a non-resilient manner when subjected to a second force applied from an offset angle to the axis.
